Abstract

An injection-molded article that can allow the position of the weld line in the opening to be displaced greatly is provided. The injection-molded article includes a plate-like member in which an opening is formed in the vicinity of an edge of the plate-like portion. Here, the plate-like member has a suspending portion closer to the edge than the opening, a base portion facing the suspending portion with the opening interposed therebetween, and two side portions that are located between the base portion and the suspending portion and that face each other with the opening interposed therebetween, and is formed by injection by allowing a resin to flow from the base portion. A recessed portion having a shape continuous from the inner circumferential surface of the opening and extending so as to get apart from the inner circumferential surface of the opening is formed on one of the side portions.

Claims

exact text as granted — not AI-modified
1 . An injection-molded article comprising a plate-like member in which an opening is formed in the vicinity of an edge of the plate-like member,
 wherein the plate-like member has a suspending portion closer to the edge than the opening, a base portion facing the suspending portion with the opening interposed therebetween, and two side portions that are located between the base portion and the suspending portion and that face each other with the opening interposed therebetween, and is formed by injection by allowing a resin to flow from the base portion, and   wherein a recessed portion having a shape continuous from the inner circumferential surface of the opening and extending so as to get apart from the inner circumferential surface of the opening is formed on one of the side portions.   
   
   
       2 . The injection-molded article according to  claim 1 , wherein a longitudinal recessed portion extending from the recessed portion toward the edge is formed. 
   
   
       3 . The injection-molded article according to  claim 1 , wherein the plate-like member is molded by injection by allowing the resin to flow from the base portion close to the side portion opposite to the side portion in which the recessed portion is formed. 
   
   
       4 . The injection-molded article according to  claim 2 , wherein the plate-like member is molded by injection by allowing the resin to flow from the base portion close to the side portion opposite to the side portion in which the recessed portion is formed. 
   
   
       5 . The injection-molded article according to any one of  claims 1 , wherein an engaging piece sliding groove extending from the edge to the opening is formed in the suspending portion. 
   
   
       6 . The injection-molded article according to any one of  claims 2 , wherein an engaging piece sliding groove extending from the edge to the opening is formed in the suspending portion. 
   
   
       7 . The injection-molded article according to any one of  claims 3 , wherein an engaging piece sliding groove extending from the edge to the opening is formed in the suspending portion. 
   
   
       8 . The injection-molded article according to any one of  claims 4 , wherein an engaging piece sliding groove extending from the edge to the opening is formed in the suspending portion.
